The technical guys removed it. Nope, my Windows XP's c: [OS folder]\system87\drivers folder doesn't have it. And nope, automatic driver search doesn't work.
Also, the machine doesn't have CD/DVD drive and I don't have the Windows XP CD.
Hit the enter key, scan will run and replace any missing or corrupted windows system files and drivers.
EDIT: For XP you do not need to open an elevated command prompt, just open cmd and run the same command, it will however ask for your Windows XP install cd.
Download and let that tool find out the hardware id of the USB-device you have in your machine.
This should replace the usb drivers that are included in Windows 7.
